A paper by Ethan Hull, PhD, President/CEO, PHDS Corporation, USA


Historically, radioactive material detection and localization have been accomplished through the semi-random movement of a detector in the presumed vicinity of the radioactive materials. This non-ideal search technique is subject to user perception errors, detector saturation and the radiation-dose and criticality hazards associated with close-proximity intervention. New compact high-resolution gamma-ray imagers provide the sensitivity and specificity to comprehensively assess the complete radiological situation from safe standoff distances before near-field intrusion. These portable high-resolution gamma-ray imaging detectors offer CBRNE teams an intuitive visual map of the radioactive material locations, identities and quantities. Both real-time on-screen information and reachback data transmission allow the team to determine the most effective threat mitigation strategy while minimizing risk to personnel. The semiconductor crystal, detector, electronic, software and imaging science are now at a manufacturing level to avail these benefits to the CBRNE responder in a portable footprint. In addition, the science and manufacture of these imagers has now been complemented by real-life measurements by CBRNE teams against relevant scenarios. Live CBRNE exercises have revealed multiple-source configurations, distributed-source shapes and quantitative information that could not have been discovered without the nuclear-visualization provided by gamma-ray imaging.
